Ms. Mu from Zhengzhou, Henan Province took her son for an eye examination when he was 1 year old, and found that the diopters of both eyes were 600 degrees and 650 degrees respectively. Both her and her husband have myopia of about 600 degrees. The doctor judged that the child carries a high myopia gene and a pathological myopia gene. After the child wore glasses, Ms. Mu also took a series of prevention and control measures, but after taking her 1-year-old and 10-month-old son for an examination recently, the axis of the left eye grew by 1.16 mm, and the degree increased by at least 100 degrees.

Is myopia hereditary? How to prevent and control young children? Ai Likun, Chief Physician of Strabismus and Pediatric Ophthalmology Department of Beijing Tongren Hospital, said that pathological myopia is different from what we often call juvenile myopia. The latter usually occurs gradually due to excessive use of eyes, such as reading books and using electronic products, and the age of onset is average. Be of school age or junior high school. Part of pathological myopia is due to genetic factors, such as parents who do carry high myopia genes, and newborns are prone to high myopia; some people are due to genetic mutations, that is, both parents are normal, but the child is born. High myopia.

In addition to pathological myopia, what is often called general myopia is also affected by genetic factors. Ai Likun said that myopia is affected by genetic factors and environmental factors. If the parents have high myopia, the child will be more susceptible to juvenile myopia, but this is not hereditary. There is high myopia at birth. From the perspective of treatment, there is no particularly good method except wearing glasses to correct it. Moreover, with age, the degree of this part of the population increases faster than the average person, and they are more prone to pathological changes, such as myopia-related fundus degenerative changes, retinal detachment, strabismus, etc.

How to judge whether it is pathological myopia? Ai Likun introduced that relative distinctions will be made in clinical diagnosis and treatment, including the time of onset, degree, speed of progression, and the effect of vision correction of the patient. Many patients with pathological myopia have poor vision correction.

In terms of prevention and control, pathological myopia is the same as ordinary myopia, that is, use less eyes, pay attention to rest, correct sitting posture, and appropriate outdoor activities. “A lot of pathological myopia combined with amblyopia have a high probability, and amblyopia treatment is needed, but this kind of situation hardly occurs in ordinary myopia.” Ai Likun added. General myopia is called refractive error. In fact, it is a problem of refractive status. The eyes are healthy. It is recommended to have an eye examination once a year. Pathological myopia is a disease that requires strict regular follow-up visits.
